4.3 Installing a communication interface module

DANGER
Electric shock
Death or serious personal injury
- Switch off the power supply to the motor and to the
signal relays. Wait at least 5 minutes before
starting any work on the motor. Make sure that the
power supply cannot be accidentally switched on.
Always use an antistatic service kit when handling
electronic components. This prevents static electricity
from damaging the components.
When unprotected, place the component on the
antistatic cloth.
